build fail

[OrenGitHub]

Hi! I can't seem to build your project:

$ ../../Downloads/gradle-6.7/bin/gradle build

FAILURE: Build failed with an exception.

* Where:
Build file '~/GIT/r8/build.gradle' line: 9

* What went wrong:
A problem occurred evaluating root project 'r8'.
> Failed to apply plugin 'com.google.protobuf'.
   > Could not create an instance of type com.google.protobuf.gradle.ProtobufSourceDirectorySet.
      > 'void org.gradle.api.internal.file.DefaultSourceDirectorySet.<init>(java.lang.String, java.lang.String, org.gradle.api.internal.file.FileResolver, org.gradle.api.internal.file.collections.DirectoryFileTreeFactory)'
